Nta
-Cov feem pua ntawm cov pa roj carbon ntau: Cov ntsiab lus carbon ntawm peb GPC siab dua 98.5 feem pua
-Low sulphur: Cov ntsiab lus sulfur ntawm qib siab recarburizer tuaj yeem ncav cuag 0.01 feem pua -0.05 feem pua .
-Low nitrogen: Nitrogen cov ntsiab lus nyob nruab nrab ntawm 80PPM thiab 250PPM .nws yog cov khoom zoo meej rau cov hlua hlau.
-High absorptivity: Qhov nqus nqus tuaj yeem siab li 95 feem pua. Piv nrog rau tib hom graphitized carburizer, qhov nqus ceev ntawm peb cov khoom yog sai dua.
-High graphite crystal nucleus thiab siab graphitization degree
Daim ntawv thov
1. Dav siv nyob rau hauv steel smelting tej hauj lwm, precision castings li carbon raisers;
2. siv nyob rau hauv foundries raws li kev hloov kho tus neeg saib xyuas kom muaj nuj nqis ntawm speroidal graphite los yog txhim kho cov qauv ntawm grey hlau casting yog li upgrade cov chav kawm ntawv ntawm grey hlau casting;
3. txo tus neeg sawv cev / txo qis hauv kev lag luam tshuaj lom neeg;
4. cov khoom siv refractory, thiab lwm yam
